Metal Mania (1989) boldly exposes heavy metal's satanic agenda targeting youth. Bob Larson interviews bands like Slayer and Laaz Rockit, revealing demonic lyrics, backmasking, and occult imagery designed to corrupt souls—contrasted with authentic Christian metal as the godly alternative. From the 80s satanic panic era, this isn't neutral concert footage—it's urgent media discernment calling believers to reject hellish rock rebellion and protect the next generation through faith-filled music. Powerful wake-up call against cultural poison.
